Sadly here in MA when they legalized cannabis they changed it from being a $100 civil fine if you were caught with it to now being able to hit you with a DUI and an open container criminal charge. So before they were not able to arrest people for pot possession in the car, it was funny to watch an episode of Cops filmed in Boston during that time, a frustrated cop pulling over carload after carload of kids and minorities and then writing them $100 civil fines and sending them on their way. But now that they can once again arrest you for having pot in the car I am sure once again teens and minorities with pot are the cops bread and butter.
